• Here is a link to Flask installation tutorial, http://flask.pocoo.org/docs/0.11/installation/.
• Here is the screenshot from the tutorial.

• Here is a Flask quick start guide, http://flask.pocoo.org/docs/0.11/quickstart/.
• Here is the full screenshot of the guide.

• Discussion about Bottle vs. Flask. Both are Python server side scripting that offer simplicity offer features. Here is the link to the discussion, http://stackoverflow.com/questions/4941145/python-flask-vs-bottle.

• To sum up with, Bottle is simpler than Flask. However, it is not scalable. Flask is scalable but still intended for smaller project.
• For this project keep using Python 2.x. There are some configuration necessary for Python 3.x. Changing codes into Python 3.x takes time, better use Python 2.x for this project.
• The Flask setup is done when Flask is installed in a virtual environment.
  • Move to virtual environment.
  • Run pip install flask in terminal.
• Now move to Flask quick started tutorial.
• Do not forget to restart in case the newly installed module does not working. In my case the command mkvirtualenv does not working after installation unless I restarted my computer. So, just remember to restart computer in case there is a newly installed module that does not working.
• The installation of Raspbian in Raspberry PI did not work as intended because I use faulty micro SD card.
• So please make sure to use micro SD card from good manufacture and from good store.
• Here is my Reddit thread concerning about this problem, https://www.reddit.com/r/raspberry_pi/comments/5fykn3/i_have_been_installing_raspbian_from_noobs_four/.
• Here is the screenshot of the Reddit thread.
